    ABC Hammers


    ABC Hammers, Inc. is the leading manufacturer of the highest quality, non-marring, non-sparking, non-magnetic and non-corrosive striking tools. They have been a family owned company for over 50 years.

    The original ABC Brass Hammers were developed by the parent companies, ABC Foundry and American Precision Castings. These hammers were carefully designed to provide superb balance, comfort and control for use in their foundry, pattern making, machining and tooling operations. Over the years, through exposure to customers, suppliers, industry trade associations and word-of-mouth, a market developed for the hammers. This growing demand led to the formation of ABC Hammers, Inc. As the market for ABC Hammers increased, so did the demand for industry-specific shapes, designs, sizes, weights and alloys. From construction sites to auto and body shops, and from manufacturing to mines and oil rigs, the ABC hammer is used in any high risk area where a spark can create a disaster or where the user does not want to mar or damage the striking surface.

    All components of ABC Hammers are made in the USA and are manufactured and assembled in Chicago, Illinois. And because ABC Hammers, Inc. is the manufacturer, it also has the ability to customize and personalize hammers to meet customer’s specifications. Whether it’s custom colors, corporate logos, specific head design or special alloys, ABC Hammers, Inc. is the choice when purchasing or designing a non-marring, non-sparking hammer.

    Remember WEN? They've been designing and distributing high quality and affordable power tools for decades. Founded by Nick Anton back in 1951, WEN originally made its mark by helping bring tools and electricity together (putting the power into power tools). Their research and development team played a vital role in helping to develop a variety of common everyday tools such as the chainsaw, the electric soldering gun, the electric jigsaw, the electric engraver, and the knife and wet wheel sharpeners. WEN even pioneered random orbital technology; the technology seen in most polishers, waxers, and buffers today that gives cars everywhere the streak free shine they deserve.

    Since then, their expertise has expanded to encompass a wide variety of products including drill presses, tool chests, bench grinders, nailers, miter saws, hand tools, generators, and air compressors to name a few. By 2001, only 50 years after their humble beginnings, they had already sold over 50 million consumer units. Today, WEN's headquarters can be found in Elgin, Illinois. Their goal is to help woodworkers and artisans across the world execute their wildest imaginations.
